mounted on the cleaner casing end cap'and the Other objects and advantages motor support. of the invention will be apparent from'thefollowing "specification and drawing, wherein:

Figure 1 is a longitudinal section'through the cleaner; and

Figure 2 is a section along the line 22"of Figure 1, and showing the filter frame broken away. The embod mentof the invention herein dis.- closed comprises a casing lllclosed at its suction end by, an end cap II with a surface-cleaning tool in a manner well known in the art. The end cap H is removablyr attached to the cleanerlcasing ID by a latch I3. The exhaust endof the cleaner casing is closed by a removable end cap ing tool unit in the same manner as the inlet port 42.. Casing 1B is supported upon a pair of longitudina ly extending skids l6 and along the top ofv the cleaner casing iis a handle 17 and a switch l8.

Within the-casing mpadjacent the end cap H, is a dirt-filtering bag 20. the open end of which is closed by the end'cap l I; Near the exhaust cap I4 is a motor 2! having a shaft 22 which extends into a fan chamber 23 where the shaft carries fans 2424 separated by fixed guide vanes 25, andithe fan chamber is formed with an intake port 26 and with exhaust ports 2?. The motor-fan unit is supported at its forward end by a resilient rubber ring 39 which lies along thefan chamber 23 and is supported by a fixed bulkhead 3! in the casing Ill. The rear end of the motor-fan unit is supported by the motor hub 34 being seated in a resilient ring 35 mounted in an annular seat 36 formed in a bulkhead 3'! which extends completely across the interior of the casing Hi and is fixedly secured to the latter. A plurality of apertures 38 are provided in the bulkhead 31 for passage of air therethrough.

The exhaust end cap it! is provided with a dome portion 39, an annular side wall it and a transverse partition 49. The side wall in has a rabbeted portion ti which extends within the casing I0, and a plurality of screws 42 extend havingvan inlet port 12 adapted to receive the cleaner end'ofan unsh'own dusting tool h'ose provided at'its opposite end M-having an outlet port adaptedlto receive the cleaner end of a dustient ring 35' for the motor through the latter into-the side wall so to re 55 edgeof the side motor and-"the wall of movably secure the end cap M to the casingll]; The inner surface of the side wall is provided with a plurality of annularly spaced ribs $43, the

free ends of which are spaced from the "inner:- wall 40 to 'form" a plurality of i which form a support "for a spaced shoulders filter;

Interposed between theendcaplland the bulkhead 3'! is a conical filter Ethavinga frame 5! formed of heavylpaperor other suitable material provided outer. peripheral edge of the supported upon the annularlyspaced shoulders 45 in" the'=end cap M 'and"the*innerperipheral edge of'the filter is "supported upon the flange" 343, the interior surface of which seats the resil housing hub 34. In operation of the device, the dirt-laden air is drawn through a suitable dusting tool unit connected to the inlet port l2 in theend cap I! and passes into the filter bag 2|] which removes from the air stream the terial, and the cleaner through the bag Zllinto the inlet port 26 of the fan chamber 23 and is then exhausted through ports 2-'i'into-' the space within'the casing surround ng the motor 2i. The air then passes through the apertures suspended foreign 'mathrough the apertures 52 of the filter frame 51 and'thence through the'opening l5 into the surrounding atmosphere. The'contour of the filter lid!" is conical andcovers the area between the the cleaner casing to .pro-. vide'a considerable filtering area.

From the foregoing tion in supporting one end of the motor-fan unit. The outer peripheral edge of the filter 5B is supported by the shoulders 45 formed in the side wall it of the end cap 9 4,

I claim:

end of said casing, a wall extending transversely the latter and with annularly spaced apertures 52 for the passage of 'air therethrough'. A suit-- able filtering material 53- is cemented on the'surfaceofithe frame 5| to remove the dirt from the air "passing throughwthe cleaner casing.

air passes outwardly 38' in the transverse wall 3'! and through thefiltering material 53 which said casing and supported by the latter and apertured for passage of air therethrough, means in asid wall forming a filter support, means in said end cap forming shoulder means to provide another filter support, and a dirt filter having its inner peripheral edge seated in said filter support in said transverse wall and its outer peripheral edge seated on said shoulder means in said end cap.

3. In a suction cleaner, a casing, suction-creating means in said casing for moving air therethrough, a removable end cap closing one end of said casing, a wall extending transversely of said casing and supported by the latter and apertured for passage of air therethrough, means in said wall forming a filter support, a plurality of spaced ribs on said end cap forming a plurality of spaced shoulders to provide another filter support, and a filter between said wall and end cap and including a perforated frame and dirtfiltering material, said filter having its inner peripheral edge seated in said filter support in said transverse wall and its outer peripheral edge seated on said spaced shoulders to support said filter in said casing.

4. In a suction cleaner, a casing, suction-creating means in said casing for moving air therethrough, a removable end cap closing one end of said casing, a wall extending transversely of said casing and supported by the latter and aperture'd for passage of air therethrough, said end cap having a side wall attached to said casing and a projecting portion extending interiorly thereof, means on said side wall forming with said pro jecting portion shoulder means, and a filter between said wall and end cap and including a perforated frame and dirt-filtering material, said filter having its inner peripheral edge seated in said filter support in said outer peripheral edge seated on said shoulder means in said end cap to support said filter in said casing.

5. In a suction cleaner, a casing, a fan in said casing for moving air therethrough, a motor in said casing for operating said fan, a removable end cap closing one end of said casing, a wall between said end cap and motor and supported by said casing and apertured for passage of air therethrough, means in said wall for supporting said motor and also providing a filter support,

transverse wall and its means in said end cap forming another filter support, and a dirt-removing filter having its inner peripheral edge seated in said filter support in said transverse Wall and its outer peripheral edge seated on said another filter support in said end cap.

6. In a suction cleaner, a casing, a fan in said casing for moving air therethrough, a motor in said casing for operating said fan, a removable end cap closing one end of said casing, a wall between said end cap and motor and supported by said casing and apertured for passage of air therethrough, means in said Wall for supporting said motor and also providing a filter-supporting flange, means in said end cap forming another filter support, and a filter between said wall and end cap and including a perforated frame and dirt-filtering material, said filter having its inner peripheral edge seated in said fiange and its outer peripheral edge seated in said another filter support in said end cap.

7. In a suction cleaner, a casing, suction-creating means in said casing for moving air therethrough, a removable end cap closing one end of said casing, a Wall extending transversely of said casing and supported by the latter and apertured for passage of air therethrough, means in said wall providing a filter-supporting flange, means in said end cap forming shoulder means to provide another filter support, and a filter between said wall and end cap and including a perforated frame and dirt-filtering material, said filter having its inner peripheral edge seated on said flange in said wall and its outer peripheral edge seated on said shoulder means in said end cap.

8. In a suction cleaner, a casing, a fan in said casing for moving air therethrough, a motor in said casing for operating said fan, a removable end cap closing one end of said casing, a wall between said end cap and motor and supported by said. casing and apertured for passage of air therethrough, means in said wall for supporting said motor and also providing a filter-supporting flange, means in said end cap forming shoulder means to provide another filter support, and a filter between said wall and end cap and including a perforated frame and dirt-filtering material, said filter having its inner peripheral edge seated in said flange and its outer peripheral edge seated on said shoulder means to support said filter in said casing.
